Background technique

Cyclone separator is a device for gas-solid or liquid-solid separation. The working principle is that the solid particles or liquid droplets with a large inertial centrifugal force are separated from the outer wall surface by the rotational movement caused by the tangential introduction of the air flow. The working principle of the vacuum cleaner is to use a motor to drive the blades to rotate at high speed, generate negative air pressure in the sealed housing, suck dust and store the dust in the filtering system.

Therefore, people will connect a cyclone separator in series at the front of the vacuum cleaner to store most of the dust in the cyclone separator, and only a small part of the dust will enter the vacuum cleaner filter. In the system, the vacuum cleaner filter element is protected, and the life of the vacuum cleaner is increased.
